due to your space issues id say having a turbo manifold that came over the turbo and sorta held the turbo in between the manifold and the block

that way the compressor outlet would be pointing upwards for ease of pipe work
and would mean it would only be about 16-17cm to the furthest point that would actually catch on anything


if you look at the pic of the turbo you might be able to see what i mean easyer looking at the orientation of the turbine inlet and the compressor outlet
